ABSTRACT

 

The paper deals with the first experiments conducted in the National Center for Hydrogen and Fuel Cell, in order to reveal the isotope separation effect in water electrolysis. Four water compositions having deuterium content in the range of natural (144 ppm) to 2%, were used to feed a PEM electrolizer, and the deuterium content of the evolving hydrogen was analyzed, revealing a slightly depletion.

 

KEYWORDS: PEM electrolyzer, water electrolysis, isotope separation
